摘要: An optical fiber bundle 10 is disclosed including a plurality of polymer optical fibers 12 disposed within a rigid sleeve 14. The fibers have been drawn to a draw ratio of at least 1:1.5 prior to placing them within the sleeve, whereupon the structure 13 is heated to induce elastic relaxation of the fibers which contract in length and expand in girth. The expansion within the rigid sleeve results in a close-packed geometry.
